Abstract
A synchronization signal includes a plurality of predetermined synchronization symbols shaped by a predeter-mined symbol pulse. A receiver (100) receives (202) a signal including the synchronization signal, and a processor (106) determines (204) a first plurality of cross-correlations between the predetermined symbol pulse and the received signal. The processor calculates (206) a plurality of sums of products of the plurality of predetermined synchronization symbols and a predetermined subset of the first plurality of cross-correlations. The plurality of sums are mathematically equivalent to a second plurality of cross-correlations between the synchronization signal and the received signal. The processor locates (208) a peak of the plurality of sums to establish receiver synchronization.
